This isn't the first time Kilmer has denied reports about his well-being. Back in January, the actor spoke up about reports saying he was hospitalized for a possible throat tumor, after he reportedly began bleeding from the throat.

"Thank you for all your sweet support. But I have not had a tumor, or a tumor operations, or any operation," he wrote on Facebook. "I had a complication where the best way to receive care was to stay under the watchful eye of the UCLA ICU. Friends have assisted who know my spiritual convictions and have been most sensitive and kind for the extra effort in making sure there's minimum gossip and silly talk. I am praying for a speedy return to the boards as they say. God bless you all and please don't worry."

Shortly after, Kilmer's rep released a statement saying he was undergoing tests at the medical center. "According to a family friend and spokesperson, the doctors are encouraged by his progress and are hopeful that Mr. Kilmer will make a full recovery," the statement read.

Kilmer's health first became a topic of conversation last December when he was spotted shopping in Malibu, California, appearing strikingly thin.
